Fiberglass is the most insulative exterior door choice due to its low maintenance feature and superior energy efficiency. Its insulation capabilities are comparable to steel doors but with a higher resistance against warping, cracking, and rotting. Steel doors offer unbeatable strength, excellent insulation, and are often more affordable than wood or fiberglass counterparts.
When building an insulated exterior door, consider factors such as wood, fiberglass, aluminum, or steel doors depending on your specific needs and preferences. Wood doors provide good natural insulation, while modern metal and glass doors often have built-in insulating features like thermal breaks and double glazing. Insulated fiberglass doors are made up of composite materials and are more secure and energy efficient than wood.
The key to choosing the best exterior door material for your home is to consider the pros and cons of fiberglass, wood, and steel. Fiberglass doors are durable and robust, offering higher energy efficiency and resistance against warping, cracking, and rotting. They require low expansion foam, which can be easily flexed with large window frames.
In terms of insulation, steel doors are highly regarded for their energy efficiency, protection, and long-lasting performance. They have a much better resistance to warping, cracking, and rotting compared to wood doors.
In summary, selecting the best insulated exterior door is crucial for improving your home’s energy efficiency and comfort. Fiberglass and steel doors generally offer the best insulation and durability, while steel doors offer superior insulation and durability.

What is the best exterior house insulation?
In cold climates, closed-cell spray foam is the best insulation for exterior walls due to its high R-value per inch, which effectively resists heat flow and serves as an air and moisture barrier. Insulating exterior walls from the inside is possible, often done in existing homes where exterior modifications are impractical. Options include blown-in cellulose for filling existing wall cavities and spray foam insulation for excellent air sealing. The R-value of the best insulation for exterior walls varies by insulation type and wall structure, and it’s beneficial to choose an R-value that meets or exceeds local building codes.
Typical R-values include fiberglass insulation (R-13 to R-15 for 2×4 walls, R-19 to R-21 for 2×6 walls), foam board insulation (R-4 to R-6 per inch), spray foam insulation (R-6. 5 to R-7 per inch), andcellulose insulation (R-3. 5 to R-4 per inch).

Is fiberglass or steel better for exterior door?
Steel is a secure option due to its durability and resistance to breakage. Fiberglass doors, on the other hand, are lightweight and easier to manipulate. Cost is a significant factor when comparing steel and fiberglass exterior doors. While fiberglass is typically more expensive initially, it offers long-lasting benefits over time. Steel may be less expensive initially but may not last as long. Professional installation is essential for both styles, with fiberglass doors being easier to install and potentially having lower costs.
What is the most energy-efficient exterior door material?
Fiberglass exterior doors are a popular choice due to their strength and energy efficiency. They are a poor heat conductor, making them energy-efficient on their own.

How to insulate an exterior door?
To increase insulation in your door, tighten all fittings and screws, strip and replace existing weatherproofing, seal glass exterior doors with heavy curtains and drapes, install a weather seal, and use draft snakes or draft blockers when not in use. A well-insulated door helps regulate temperature, keeps energy bills down, and is better at holding elements at bay. Different materials and styles are better at holding elements at bay. Simple insulated door solutions can make a big difference without spending a lot of money on a new door.
What is used to insulate doors?
Manufacturers typically use two primary insulation options for doors and garage doors: expanded polystyrene (EPS) and polyurethane (PU) foam. While EPS is often used because it’s the standard, it can be an efficient material for improving operational processes and ensuring product quality. Polyurethane, an efficient material, can perform the same job as EPS but in fewer steps, making it a more cost-effective choice for insulateng entrance and garage doors.
📹 What is the Best Insulation for Exterior Walls? | Foam University
When it comes to choosing the best insulation for exterior walls, you have a lot to choose from. In this episode of Foam University, …
I did this to my garage yesterday with 1″ board. My wife asked me what I was doing. I told her and a day later ur article popped up on my YouTube feed. When I was done I opened the door and could hear the opener struggling. I saw ur article a day later and made me look up the specs on the 1″ board. To my surprise they are 5 lbs per board. I used just under four boards. That’s just under 20 lbs added to the door. I took the door off the opener and sure enough it was harder to open by hand. I added three 1/4 turns to my spring and that seems to make up for the extra added weight. The opener sounds back to normal. I put a new spring a few years ago and up sized it from original. Thanks for the tips 👍🏽
Ok that works and looks good but you made way more work then you needed to do. Once you score the foam board just break it, done, doesn’t matter what the cut looks like, you’ll have the nice clean score line and the rest of the cut didn’t matter, it’s in the door you can’t see it Also you should have cut them at the 17-1/4″ you needed. Then you put one edge in and give it a little bend and pop the other edge in. It’ll fit tight, no spray foam needed and the lip on the garage door panel holds the foam in.
Sorry if this is a duplicate comment. Installation of this material as suggested is unsafe. Per the manufacturer, “Owens Corning Foamular products are combustible and must be covered by a 15-minute thermal barrier such as 1/2″ drywall. We do not recommend using Foamular to insulate a garage door. There are better choices such as the Owens Corning Garage Door Insulation Kit. Thank you for your inquiry!”
I am new to the insulation stuff…Seeing your article feels like I should be able to handle this project quite easily. Thank you for explaining in so much detail and also sharing testing out which one is better than the other. Really appreciate this level of details. I have a question…If I were to add multiple layers of insulation, Let’s say 2 layers of double reflective insulation, will it be better than 1 layer of double reflective insulation ?? Maybe not?
Great article – thanks!! I just ordered that rubber bottom garage door seal! Built our house 10 years ago and notice you can see a little light under the door and a little water / snow can get in. I just inspected to seal that’s on there now and oh my God it’s horrible! So excited to get this new seal tomorrow! I’m going to look at those panels also. Thanks again!!!
XPS, including the new NGX, polystyrene foam board is highly combustible and must be covered with a protective or thermal barrier to separate it from a interior living space by code in most areas. Since a garage door is exterior and not to a adjoining living area, it would probably pass code. However, not mentioning that it’s highly combustible to your viewers is a concern. Someone adding a XPS to their garage door that may do work such as welding or grinding, will find out just how combustible it is.
You can buy a foam insulation kit from some local Garage door companies. They will be cut to the right height 21″ for the top and bottom and 16″ for intermediate sections. They will be 8’ft. long so you cut them about in half depending on the width between the vertical styles where the hinge’s mount. they often have a thin white PVC pebble tec finish backing skin so the whole door is white inside. This is easy to clean when you get dusty spiderwebs on the back of the door. They are not cheap because the Garage door company wants to make a healthy profit as it is a specialty item. They are installed the same way the insulation was installed in this article. They are a snug fit and it is a bit of a wrestling match to get the panels in place. I could insulate a whole door in about 2 hours but I have a lot of experience. If I were to do this I would compare the price of the kit versus the cost of enough sheets of Owens -Corning insulation to complete the job at your local Home Depot. If you Garage gets Western sun in the afternoon this will keep the garage much cooler. However, if you pull your car into an insulated Garage after your commute home it will also keep the heat from your hot engine in the garage. The insulation will add weight to your garage doors spring(s). They may need to be adjusted to get the door to open smoothly. Call a pro to adjust the spring. It will be much cheaper than a trip to the Emergerncy Room if you try to do it with out the proper tools and knowledge and some thing slips.
Please be aware that rigid foam insulation is highly, highly flammable, and by code is not allowed to be exposed on interior finishes. And garages tend to be a location with open flame and where most house fires start. Better a proper three-layer insulated garage door with metal panels on both inside and outside faces to meet requirements in many jurisdictions and safe practice.
That is my concern that it may put too much weight on the door. I don’t know if it will be obvious. Maybe I should just install a few panels on the bottom and work my way up. Can’t seem to find a reliable garage door company in my town. There’s been a lot of negative comments on the next-door app in my neighborhood. My spring is totally enclosed
My garage door just died. It was 24 years old and had many added braces to repair fatigued metal and such. But it finally gave up the ghost, jumped the track, and almost fell on the car. it was time. Guess what? You can buy new doors that are heavily insulated with R10 or even higher. Metal on both sides, insulation in the middle. And it wasn’t that much of a percentage more money than the cheaper non-insulated one. 15% to 20% more or so. More? Yes. But not double the cost or anything. Now it is well insulated, and also far stronger and rigid. Now, it’s very much like an insulated steel front door. Big improvement. So, if you are at the point of getting a new door anyway, look at higher end double-wall insulated ones.
i did this 2 years ago with same board. but i added a sheet of bubble insulation first, then the board and then another sheet of bubble insulation. and finally i added foil tape to hold the bubble insulation and board inplace. came out really well. way less hot in the summer and less cold in winter. one thing to remember is a well insulated garage door by itself is only part of the solution. u have to make sure the space above and around the garage is well insulated or u wont get the desired temp. u want.
This may be fine for temperate climates, but not in Arizona when the sun shines on your door. The amount of radiant heat transferred by all that exposed metal not covered by the foam board (the joints and sides) is still enormous. It’s just one giant heat sync. I’m wondering if there’s some type of coating that can be applied to the entire inside surface.
Definitely need to seal around the edges of the door. My garage door is 16’ x 7’, and it really flexes inward in a strong wind, which lets rain and snow to get inside past the seals. Some things that have helped with that problem are: brush seals for outside surrounding the door, the ‘Green Hinge System’, a double-bulb rubber bottom seal, and a threshold seal. These four things have made a significant impact in reducing water and snow intrusion. Thanks for the article.
Like yourself, my garage door panels are not all equal in size so I can appreciate the “oops” moment. I’m getting ready to insulate my two double garage doors, but plan to use Johns Manville polycyanurate 1″ insulation. First of all it’s rated R-6, and secondly it is foil backed, which I will place against the inside surface of the doors to reflect the suns heat. I need all the help I can get in Arizona.
I filled the whole panel space by cutting the 40 mm thick polystyrene sheets to the correct size but in two halves. The top and bottom halves could then be angled in at the top and bottom and pushed in together in the middle creating a very tight fit. I cut two of the rows approximately 20% and 80% of the panel size as the door’s reinforcing rails would then cover the joins. The sheets have been in place for 5 years now and none have popped out. I also glued wall wrap (foil) behind the foam. I also corrected my mistake of not ordering the west facing door in white by painting it white to reflect the afternoon summer sun.
Does it really make that much difference to do the foam to fill in small gaps? In my case I was interested in reducing radiant heat from the metal panels in the afternoon summer sun. It did help a lot. However there is always air and not much insulation going on around the door edges where there is typically a thin vinyl weather flap. Heat and cold will always be leaking around there.
I used single side reflective, on thr interior side it is white. However during install i stuck it to the support struts, creating an air pocket between the insualtion and the garage door.. I notice when you did the test st the start, you sruck the reflective insulation directly to the garage door. All the DIYers ive followed have shown its far more effective creatinf an air pocket in the door, bexause obviously air doesnt transmit temperature as well – similar to the way a dry suit works much better for divers.
Always upgrade your spring with this process. The weight of the door becomes too much and places significant strain on the gears of your opener and at the top center of your garage door. It can buckle the section. If the door does not balance manually at each opening section/pivot, it is not functioning correclty. Trust me! I am an 8yr garage tech with cureently 3 yrs as a small business owner.
What is that garage door made out of, just stamped metal? That seems…. cheap. Either way, that metal framework is one massive thermal bridge, and will still suck a ton of heat out right through the structure of the door. To properly insulate you need the whole structure including the joints covered with a sheet of material, which of course is hard to do on a working garage door. Seems like just buying a properly insulated garage port door might be the sensible way to go. I know there are 2-inch thick sandwich construction doors in the US as well.
This is going to cause a lot of people to damage their garage doors. Pan style garage door sections are constructed by attaching the stiles to the door skin with tiny rivets, two on the top and two on the bottom, and then gluing the stile to the door skin in a few spots. As you press the foam into position you’re pushing the door skin away from the stile and stressing that glue. Not a big deal on a new door but as the door ages, that glue fails easily. After the glue fails, we start seeing issues that lead to replacing sections or the entire door.
A couple questions: \t1. I’m measuring 2″ from deepest point to the lip, so should I go with 2″ foam or should I get thinner boards to make room for spray foam? \t2. Do you recommend 1″ spray foam for the edges? BTW: I checked out Home Depot today and almost all the foam boards (not just the ones from NGX) were crushed in various places. They only had two NGX boards and both had damage, so I’m hoping I can get four good ones.
I have sold garge doors for 25 + years. Your garage doors springs are calibrated to the factory weight of the doors. The spings are the doors counter balnce system that lifts the weight of the door making it light and easu to open. When you add weight to a garage door, you are throwing the counterbalance of your door off. After adding weight, the springs need to be recalibrated. This is done with a special scale that a garage door service company would have. In other words, you can’t just add insulation to a garage door that wasn’t designed for it. It will eventually take your open out.
I used a gun for canned foam to fill all those C cavities and make sure all parts were as insulated as possible. Because those cavities have holes, you can spray foam into the cavity after the install instead of pulling anything off. ALSO, I have windows across my top row. I cut 1″ board to go around those. Worked out really well. Wish I could post pics here to share.
My garage door SUCKS! Is there a kit for garage door panels that measure 16″x16′ (approx.)? Also, these panels don’t have the nice over hanging lips to tuck the foam insulation into. And yes, I hate my garage door! It’s like a one-off where there are so many aftermarket parts but don’t fit my garage door! Frustrating to say the least. Thanks for any help y’all may provide!
Engineer-architect here. Did you insulate your house windows as well? Even with double glass they will loss quaty a lot of heat…..however, the ideal will be insulate the water pipes so doesn’t freeze (and turn down the heat) because, what is the point to keep an empty house warm and pay a high energy cost just to keep the pipes safe? Also, build smaller houses with smaller windows will help a lot Americans don’t know to build houses efficiently, so they keep paying mortgages, high taxes and high maintenance costs
so i too want to cool down my garage went to a local auction company and picked up 20 panles of 2 in foam board for $125 then started researching on how to glue or tape them in. saw you article at number one and i watched it, then watched the previous one. so then i checked the temps in my garage and my door was about 105* and walls were about 110. then i checked my roof and it was 135*. i saw you house has a room above it so you dont have to worry about heat from the top. would using 2″ foam for the roof be a good idea also?
‘Cold’ can’t come through. Cold is merely less thermal energy. Thermal energy is leaving the room through convection and our bodies sense transfer of thermal energy not temperature. That’s why a piece of metal and a piece of wood despite being the same temperature feel different. The metal easily conducts thermal energy out of our bodies while the wood doesn’t. NGX is a good product for insulating a garage door, but you’ll need to get the garage door springs adjusted to compensate for the extra weight of the door so the opener motor doesn’t have a shortened life.
best way is to hire a pro that knows what he is doing ..not just a slam it in the hole an run guy..and ps dont buy a cheapo door expecting quality either…get a good double sided metal door with encased insulation…o ..the add on insulated doors are ok but you get what you pay for… I have installed many good Midland insulated doors over the years they are very hard to beat, top of the line doors that are more secure and will last you a lifetime …unless you forget to open em when you drive thru….wink wink…and get a decent operator ..aka opener … those are the noise sources if your wanting quietness.. i’d recomend a belt drive ……happy hunting …..10 plus years installing doors says that diy may sound good…. but over the life of the door done correctly usually wins especially when most decent installers warranty their work….suit your self… if you have the time to fiddle with the door continually and like doing that get at it …. have fun and above all….. please don’t get hurt …them springs can be dangerous….
I would’ve done it a bit differently by installing each panel as 2 pieces, (an upper and a lower) so that the factory edges meet in the middle and there wouldn’t be any need for spray foam. The difference in aesthetics due to a seam in the middle is no concern of mine. The factory edges should seal against each other just fine. For aesthetics, I would cover the entire inside of the door with thin vertical panels that cover all the hardware and seams. If the final layer is thin enough, you may not even have to make any horizontal cuts.
I bought and installed a box of the fiberglass stuff and even on the box it says if installing two boxes on a two car door, you need to adjust spring tension to account for the weight. How heavy are these foam boards compared to the fiberglass? I only have one box for the time being so not really an issue weight wise as is, although I can definitely feel it already when raising/lowering the door.
All of my local hardware stores say 1.5 is out of stock and unavailable online or in stores. Sigh. Thinking of going with 1″ with some of the reflective bubble wrap. I’ve never tackled something like this, but think I could do it with some help. OR, should I go with 2″ and just angle the edges so they fit in the websites? I really appreciate the article and comments.
I have similar, I was wondering if you could do each section in halves along the long dimension, and push each half in to the groove at the top and the bottom so the foam goes in to where you put the spray foam, they should jam in against each other, or a thin strip of something could be put in from top to bottom to hold them in.
Honestly, I don’t think you need to bother with the spray foam, the metal curls around anyway, so there there’s a giant thermal bridge through that metal. And the air inside can’t really move anywhere because it’s a very very small pocket, so it really doesn’t help you all that much to insulate it as the heat is going to go around the edge rather than the air that’s already trapped.
I would love to see another article dealing with the sealing and noise of the door I’ve been researching some products but don’t know if it’s worth pulling the trigger on them ThermoTraks sealing system ThermoTraks bottom seal retainer and seal Green Hinge spring loaded energy sealing hinge set Dura-Lift / ThermoTraks nylon rollers Quiet / silent roller sleeves
You used the wrong seal. There is a way better seal that has a solid piece attached to it. You put sealer between the solus piece and your wall, screw it on so it has a little pressure on the door. They seal so well you get no light. And. It is printable. However. Good job overall. You married? I have a stray daughter.😅
I don’t get why you’d use this NGX stuff (XPS = styrofoam) vs PolyIso insulation boards which are R-6.5+/inch vs NGX at only R5/inch. Plus the polyiso has foilbacking for reflecting heat. For a small surface area like a garage door where the time and labor are way bigger than the cost of materials, it makes sense to use the good stuff!
